can anyone tell me if it will charge 2 samsung galaxy phones simultaneously? does it care that one port is higher rated than the other?

dont know, because i am not using it for phones, but tablets, but the have higher amp use then a phone does, so, only makes reason, that you can

I've had my particular charger charging both my Samsung Galaxy S3 and my friends Samsung Galaxy Nexus. It doesn't seem to "care" that one port is higher rated but you will notice the 2A port charging nearly twice as fast.

I frequently charge my Samsung Galaxy Tab2 Tablet and my Galaxy S4 phone simultaneously

Should be no problem. Current rating is just the max a port will provide. If the phone needs more than the current is can provide it will just charge slower.

I've used both ports for my galaxy S2 and also used one for my phone and another for my nexus 7 at the same time. Just use the 2A port for whichever device requires more power or in the absence of such a distinction, whichever device you wish to charge faster.

Yes it will charge off of both ports at the same time.No my Galaxy III does not care if it is on the higher port.

This device will not charge two tablets (2.1a) at the same time. It will charge a phone and a tablet or two phones at the same time.

Yes, it can charge both devices at the same time. I don't have any information, though, about charging rates in that situation.

This is great! I have galaxy mega and hubby has a galaxy s5 and it charges both together faster than separate wall chargers. Very durable. Plus u get 2 in case u lose one. Highly recommended! Hope this helps!

most certainly! I have had two devices charging at the same time with no problem. Certainly one item charges faster but all in all the charger is real quick on recharges and you shouldn't have a problem good luck!

I was not able to charge more than the specified devices. The 5 ports have different output levels, and I found that one of my phones will not charge if it's not plugged in to the right type.It works exactly as advertised--different outputs for different device types. It won't charge device types that don't match and that cannot handle the output level.

Definitely. It's designed to charge an iPhone (or a different smartphone of similar capacity) and a tablet at the same time, with an "S" slot and an "A" slot, one for a tablet and one for a smartphone. However, the max Amps the entire charger outputs at once is 2.4 amps, and amps are what actually adds charge to your device's battery. One slot gets priority for amps when both are being used but I'm not sure which one. But basically yes it should definitely be able to charge those two phones at the same time.

I use both ports for phones including my Samsung galaxy phones with no problems although they do charge a bit faster on the 2.4A port

This charges both tablets and phones. The ports are labeled, one for tablet, the other for phone. The tablet port delivers a higher charge to recharge tablet faster

I can't say for certain since I don't have three android phones to try it. But it should split the 5 amps between the devices. So 1.7 amps each. If it does charge it won't be very fast.

I'm pretty sure either one will be the same. Most chargers like this are a parallel circuit so there is no number one port, per se. The ports output equal amps unless marked.

I know what you want to know, but your question has a slight error. You want to know how many mA (milli-Amps) this device puts out- not how many mAh (milli-Amp-hours). From the product description: Dual USB Charging Ports: Provides 1.0 amp of current when charging one device, and 0.5 amps of current to each port when charging two devices from AC or DC power. For AA or 9V charging, single port charging is supported. DC 5V +/- 5% 1000mA MAX So if your device is capable of absorbing 1000 mA (1 A), and you leave it connected for 1 hour, you would deliver 1000 mAh. Two hours, 2000 mAh, three hours, 3000 mAh, and so on. It's perhaps a fine distinction but it is important. HOWEVER- I think you may be disappointed if you try to use this as your primary charger for a device that requires 2100 mA of charging current (note I did not include the 'h'). It will only deliver 1A maximum, so if your Galaxy Tab will even charge from this device, it will take approximately twice as long as it would to charge from the Galaxy Tab's original AC adapter. HTH

This model sucks as far as that is concerned get the one off ebay that doubles ad a jump pack and laptop charger. But to answer your question It only charges one at a time. The two ports are a 1.5 amp and a 0.5 amp port either way I have had devices on this thing and they never filled up... they will continue running but filling one up is never really easy... also check into spare batteries for your phone on ebay... they are usually only like $5.00 so good deal...

Correct... I haven't tested to see which port(s) would be 'ramped down', but the effect would be that one or more devices would charge a bit more slowly. Chances are good they will all charge, and pretty fast (you're only "missing" 200mA), but it won't be all three devices at full speed.

I have charged my Galaxy S4 on both. It charged quicker on the 5V2A slot it seems.

I can't speak specifically to two Galaxy S3 phones at the same time but we often simultaneously charge two iPhones or an iPhone and an iPad and we have never had a problem.

I believe this will work for any standard USB port end charger cord - I use it for my Kindle and Iphone at the same time and it charges both of them fully - I love it; bought 4 more to give my kids for Christmas. Can't speak directly to Samsung use because I don't have a Galaxy, but if it's USB, it's USB, right? Hope that helps,
